[QUOTE="unlacedgecko, post: 8098030, member: 19130"] I've messaged you on Facebook messenger. I'm banned on Facebook currently so can't post. F1, F2 are standard breeding term for cross breeding. Both Rosie and I know what we're referring to with F1, F2 etc. It's easier for us to say that than 1/2 Shetland, 1/4 Shetland etc. We also both have a real keen interest in genetics, recording and sheep breeding. I'm always listening to podcasts on breeding or grassland management or livestock. I've been planning this flock for the last 8 years. Being able to action those plans is really exciting and gets me out of bed every day. Yes, grading up "wee island rats" to a commercial shedding composite is exactly what I/we are doing. They could be called easycare, but that's a trademarked name. And I haven't looked into the breed spec in detail. From a £20 draft ewe and a couple of years of breeding I'll potentially have an animal which can match a NCM in production, but with far less maintenance. The myomax is to counteract the Shetlands poor shape. Each copy adds 5-7.5% lean meat yield on the hind quarters. So it should improve confirmation without compromising lambing ease. Here's an in depth explanation of myomax. [URL]https://www.easycaresheep.com/news/2020/the-myostatin-gene-explained[/URL] The inverdale is to dramatically increase the Shetlands small litter size. Here's an explanation of inverdale. [ATTACH type="full" alt="706048-ae4158a0c2e79ee12ff91ca4770cf67f.jpg"]1030463[/ATTACH] 80% of infertile ([COLOR=rgb(184, 49, 47)]X X[/COLOR]) ewe lambs can be identified at lamb marking be their deformed nipples. The remainder won't cycle, so could be negatively identified by raddled teasers, or by being empty at scanning. But I'm a few years off any such ewe lambs being bred. What am I hoping to achieve as an end point? A flock of ewes with the following characteristics 55-60kg Hair type coat shedders Excellent feet and teeth Scan over 200% Give birth unassisted Wean triples to commercially viable weights Rebreed on time 20-25% annual replacement rate Do all the above solely off grazed forage. In short, I want a very efficient low input high output flock. All flock ear tags are marked LIHO. At some unspecified point in the future I may offer breeding sheep for sale. But I'd want to performance record them beforehand, so that's some way off. It's hoped that a clean shedding double myomax inverdale ram will be born this month. If not, he will definitely be born next year. As per the diagram above I will need to test these lambs to discover if any match my requirements. Once this animal is born he will be used on the F1 and F2 females. In later years the LIHO rams may be used directly over Shetland drafts to produce a mule type female for sale. Or I can use them to rapidly expand my flock as the land situation requires. All the F2 lambs being born this year will be at least single myomax. That's how genetic inheritance works, as they were sired by a double myomax ram. As far as I'm aware, there is no one else breeding inverdale shedders. If you know of someone please let me know as I'd be keen to speak to them. I'm more than happy to answer any other questions here or on Facebook messenger. [/QUOTE]
